BACKGROUND

The present disclosure relates generally to hunting decoys, and more particularly to waterfowl, e.g., duck decoy deployment systems.

Most known waterfowl decoy deployment systems are used by hunters to attract waterfowl, such as ducks, so that wild waterfowl are attracted to the decoys and will be brought into shooting range. Many of these known waterfowl decoy deployment systems use submerged components that are spreadable when deploying and collapsible when retrieving. Such known deployment systems typically include a plurality of decoys tethered in some manner to one or more extendable and retractable arms. Many of these known deployment systems experience similar problems. One such problem is that the systems are difficult to deploy and retract since they require some sort of mechanical operation by the hunter. Use of a large numbers of decoys is desirable in order to better attract waterfowl. However, the time and effort needed to deploy and retract decoys becomes more difficult as the number of decoys increases. In addition, storing, deploying, and recovering a large number of decoys on a single system further increase in difficulty because of the tendency of the tethering lines and the decoys to become entangled with each other. Some known waterfowl decoy deployment systems alleviate entanglement of the tethering lines; however, such known systems rely on arms at different heights, i.e., height indexing with respect to a center hub to accommodate a substantial amount of hardware within the hub. Moreover, since most waterfowl hunting seasons are in autumn and winter, increasing the amount of time spending deploying and retracting decoys adds another layer of difficulty to a recreational venture.

DETAILED DESCRIPTION

The exemplary apparatus and systems described herein overcome at least some disadvantages of known waterfowl decoy deployment systems by providing a hub subsystem and a decoy tether guide subsystem to simplify deployment and retrieval of a large number of duck decoys while mitigating entanglement of the decoys and their tethers. Specifically, a hub cap on the top of the center casing of the hub subsystem uses a portion of the decoy tether guide subsystem to route the plurality of tethers from the hub cap to a plurality of deployably extendable and flexibly collapsible arms, where another portion of the decoy tether guide subsystem routes the individual tethers to the respective decoys. In addition, a unique spring-collet-collet nut assembly forms a biased arm suspension mechanism for each arm, where the biased arm suspension mechanisms facilitate arranging the configuration of the arms and tethers to not require any height indexing thereof to reduce a potential for tether entanglement. As such, the decoy tether guide subsystem described herein facilitates quick, independent, and automatic operation of a plurality of deployably extendable and flexibly collapsible arms extending therefrom. Additionally, the decoy tether guide subsystem facilitates mitigating a potential for entanglement of the decoys and their respective tethers. Furthermore, the waterfowl decoy deployment systems described herein a unique slot system for coupling devices, such as motive devices, to the waterfowl decoy deployment system, thereby facilitating substantially synchronized motion of the decoys.

FIG. 1 is a schematic perspective view of an exemplary waterfowl, i.e., duck decoy deployment system 100. Alternatively, decoy deployment system 100 is adaptable for any other waterfowl including, without limitation, geese and swan. Duck decoy deployment system 100 includes a hub subsystem 102 located substantially at a center portion of system 100. Duck decoy deployment system 100 also includes a plurality of deployably extendable and flexibly collapsible arms 104 coupled to, and extending radially outward from, hub subsystem 102. In the exemplary embodiment, system 100 includes six substantially identical, fixed length arms 104. Alternatively, system 100 includes any number of arms 104 having any configuration including, without limitation, varying lengths and materials. Duck decoy deployment system 100 further includes a plurality of waterfowl, i.e., duck decoys 106 coupled to each arm 104 through a respective decoy tether 108, where some of tethers 108 have varying lengths (discussed further below). In the exemplary embodiment, system 100 includes at least one duck decoy 106 coupled to each arm 104, where, in the exemplary embodiment, two duck decoys 106 per arm 104 are shown for a total of twelve decoys 106.

Duck decoy deployment system 100 includes a plurality of arm suspension mechanisms, i.e., a spring adaptor assembly 114. Each spring adaptor assembly 114 is inserted into a respective arm aperture 112.

In the exemplary embodiment, there are six spring adaptor assemblies 114 positioned approximately 60° apart from each other along circumferential perimeter P of casing 110. In general, spring adaptor assemblies 114 are positioned about circumferential perimeter P of casing 110 at circumferential positions of approximately 360 degrees divided by the number of arms 104. As such, hub subsystem 102 is substantially symmetrical.

FIG. 13 is a schematic side view of hub cap 116. FIG. 14 is a schematic bottom view of hub cap 116. Referring to FIGS. 11-14, hub cap 116 includes an outer lip 202 coupled to and extending from a top surface 204. Outer lip 202 contacts upper flange 126 of casing 110 (both shown in FIGS. 2-5) to define a stand-off distance between top surface 204 and flange 126 to facilitate routing tethers 108 (discussed further below). Hub cap 116 also includes an inner lip 206 that extends from top surface 204 a greater distance that outer lip 202. Inner lip 206 extends into interior chamber 136 to form a friction fit with casing 110 proximate upper flange 126 such that hub cap 116 remains removably coupled to casing 110.

Decoy tether guide subsystem 200 includes hub cap 116 and upper flange 126 of casing 110. Hub cap 116 includes a plurality of tether guides in the form of a plurality of radially inner decoy guide openings 208 and a plurality of radially outer decoy guide openings, i.e., pairs of tether guide openings 134. In the exemplary embodiment, radially inner decoy guide openings 208 and tether guide openings 134 are substantially circular. Radially inner decoy guide openings 208 have a diameter D_(Inner) and tether guide openings 134 have a diameter D_(Outer), where D_(Inner) is greater than D_(Outer). The values for diameter C_(Outer) are selected to accommodate a plurality of tethers 108. The values for diameter D_(Inner) are selected to accommodate a single tether 108 to facilitate reducing a potential for entanglement of tethers 108. In a manner similar to tether guide openings 132 in upper flange 126 (both shown in FIG. 2) and pairs of tether guide openings 134, radially inner decoy guide openings 208 are positioned approximately 60° apart from each other along top surface 204 of hub cap 116. In general, radially inner decoy guide openings 208 are positioned about top surface 204 at circumferential positions of approximately 360 degrees divided by the number of radially inner decoy guide openings 208. Alternatively, radially inner decoy guide openings 208 and tether guide openings 134 have any shape, configuration, and orientation that enables operation of system 100 as described herein.

Also, in the exemplary embodiment, tethers 108 are terminated proximate radially inner decoy guide openings 208. Decoy tether guide subsystem 200 further includes a plurality of tether securing devices 210, each tether securing device 210 coupled to a respective tether 108. Moreover, each tether securing device 210 has a size and a configuration that facilitates devices 210 contacting a bottom surface 212 to reduce a potential for devices 210 to traverse through the associated radially inner decoy guide opening 208, thereby securing the associated tether 108 to the underside of hub cap 116.

Further, in the exemplary embodiment, each tether 108 extends upward from respective tether securing device 210 through respective radially inner decoy guide opening 208 to a respective tether guide openings 134 along top surface 204 of hub cap 116. Tether 108 extends downward through tether guide opening 134 and through tether guide opening 132 of upper flange 126 toward a respective arm 104 (shown in FIG. 2).

Moreover, referring to FIG. 11, in the exemplary embodiment, a first decoy tether 214 extends from a first radially inner decoy tether guide opening 208 to one radially outer decoy tether guide 216 of a first pair of radially outer decoy tether guides 218. Also, a second decoy tether 220 extends from first radially inner decoy tether guide opening 208 to another radially outer decoy tether guide 222 of a second pair of radially outer decoy tether guides 224 adjacent first pair of radially outer decoy tether guides 218. Further, a third decoy tether 226 extends from a second radially inner decoy tether guide 228 to another radially outer decoy tether guide 230 of second pair of radially outer decoy tether guides 224.

FIG. 17 is a schematic longitudinal view of a portion of deployably extendable and flexibly collapsible arm 104. FIG. 18 is a schematic overhead view of a portion of deployably extendable and flexibly collapsible arm 104. A first guide device 242 and a second guide device 244 are coupled to arm 104 and positioned proximate each other. Guide devices 242 and 244 are eye bolts. Alternatively, guide devices 242 and 244 are any devices that enable operation of systems 100 and 200 as described herein, including, without limitation, tubular conduits.

First guide device 242 and second guide device 244 are indexed. i.e., they are separated with an angle θ and a distance X. Angle θ includes values within a range between approximately 30° and 45°, where in the exemplary embodiment angle θ is approximately a 45° angle. Distance X has a value of approximately 1.5 inches (38.1 mm). Alternatively, angle θ and distance X have any values that enable operation of system 100 as described herein. First guide device 242 and second guide device 244 are indexed to facilitate significantly reducing a potential for second decoy tether 220 and third decoy tether 226 to become entangled with each other. Second decoy tether 220 is threaded through first guide device 242 and third decoy tether 226 is threaded through second guide device 244. Second decoy tether 220 is coupled to first duck decoy 232 through a coupling device 246. In the exemplary embodiment, coupling device 246 is a crimped fastener. Alternatively, any coupling device that enables operation of systems 100 and 200 as described herein is used, including, and without limitation, waterproof tape.

FIG. 19 is a schematic perspective view of another portion of deployably extendable and flexibly collapsible arm 104. FIG. 20 is another schematic perspective view of the portion of deployably extendable and flexibly collapsible arm 104. Decoy tether guide subsystem 200 includes a third guide device 248 (only shown in FIG. 19) and a fourth guide device 250 (only shown in FIG. 20). Guide devices 248 and 250 are eye bolts. Alternatively, guide devices 248 and 250 are any devices that enable operation of systems 100 and 200 as described herein, including, without limitation, tubular conduits.

Third decoy tether 226 is threaded through third guide device 248 and fourth guide device 250. Third decoy tether 226 is coupled to second duck decoy 234 through coupling device 246. In the exemplary embodiment, coupling device 246 is a crimped fastener. Alternatively, any coupling device that enables operation of systems 100 and 200 as described herein is used, including, and without limitation, waterproof tape.

Referring to FIGS. 1 through 20, in operation, duck decoy deployment system 100 is initially in a folded or collapsed condition, where arms 104 are substantially parallel to the longitudinal direction and handle device 118. As such, spring adaptor assemblies 114 have approximately a 90° bend upward. System 100 is lifted by handle device 118, and an anchor line 180 is coupled to anchor eye bolt 124, looped about at least two line slots 130, and coupled to an anchor device for facilitating substantially reducing a potential for translation of system 100 due to water currents. Line slots 130 are also configured to receive an optional motive device (not shown) therein, where line slots 130 are configured to couple the motive device to casing 110 to facilitate motion of duck decoys 106. System 100 is dropped into water of a predetermined depth, e.g., and without limitation, within a range between approximately 20 feet (6.1 meters) and 25 feet (7.6 meters).

While in the collapsed position, arms 104 are restrained with any restraining device that enables operation of system 100 as described herein, including, without limitation, a restraining band and rope. The restraining device is removed and arms 104 drop through gravity into the water into the extended, i.e., deployed condition. Hub subsystem 102 and the weight pull hub subsystem 102 below the surface of the water toward the bottom with a gradual submergence over time in contrast to a rapid sinking. As such, the weight coupled to anchor eye bolt 124 is selected based on the weight and buoyancy of system 100 as a whole, thereby establishing a relative neutral buoyancy for system 100. Arms 104 drop below the surface of the water and the buoyant duck decoys 106 float on the surface, thereby preventing further sinking of arms 104. Hub subsystem 102 eventually sits within a range between approximately 12 inches (30.5 centimeters (cm)) and 24 inches (61 cm) below the surface of the water, at least partially depending on the length of tethers 108. As such, with the exception of decoys 106, system 100 is substantially submerged and not visible to incoming waterfowl.

As arms 104 drop, each decoy tether 108 slides through the respective guide device 242, 244, 248, 250 and is at least partially restrained by the respective tether securing device 210, radially inner decoy guide opening 208, radially outer decoy tether guide 216 of the pair of tether guide openings 134, and tether guide opening 132 in upper flange 126. Such restraint of tethers 108 facilitates significantly decreasing entanglement of tethers 108 during deployment of system 100. Also, the indexing of guide devices 236 of decoy tether guide subsystem 200 as described above facilitates ease of deployment of system 100.

Hub subsystem 102 is free to rotate with the natural currents of the water and the wind. Therefore, arms 104, with duck decoys 106, are free to rotate with hub subsystem 102 with movements that simulate natural duck movements. Also, in operation, system 100 is retrieved through grabbing hub subsystem 102 through wire loop 120 coupled to handle 138, lifting system 100 out of the water, and placing into a bag-like transport device to place arms 104 into the collapsed position. Restraint and indexing of tethers 108 for deployment as describe above also facilitates significantly decreasing entanglement of tethers 108 during recovery of system 100.

The exemplary apparatus and systems described herein overcome at least some disadvantages of known waterfowl decoy deployment systems by providing a hub subsystem and a decoy tether guide subsystem to simplify deployment and retrieval of a large number of duck decoys while mitigating entanglement of the decoys and their tethers. Specifically, a hub cap on the top of the center casing of the hub subsystem uses a portion of the decoy tether guide subsystem to route the plurality of tethers from the hub cap to a plurality of deployably extendable and flexibly collapsible arms, where another portion of the decoy tether guide subsystem routes the individual tethers to the respective decoys. In addition, a unique spring-collet-collet nut assembly forms a biased arm suspension mechanism for each arm, where the biased arm suspension mechanisms facilitate arranging the configuration of the arms and tethers to not require any height indexing thereof to reduce a potential for tether entanglement. As such, the decoy tether guide subsystem described herein facilitates quick, independent, and automatic operation of a plurality of deployably extendable and flexibly collapsible arms extending therefrom. Additionally, the decoy tether guide subsystem facilitates mitigating a potential for entanglement of the decoys and their respective tethers. Furthermore, the waterfowl decoy deployment systems described herein a unique slot system for coupling devices, such as motive devices, to the waterfowl decoy deployment system, thereby facilitating substantially synchronized motion of the decoys.

An exemplary technical effect of the above-described waterfowl decoy deployment systems, hub subsystems, deployably extendable and flexibly collapsible arms, and decoy tether guide subsystem and methods includes at least one of the following: (a) simplifying deployment and retrieval of a large number of duck decoys while mitigating entanglement of the decoys and their tethers; (b) using a hub cap on the top of a casing of a hub subsystem as a portion of the decoy tether guide subsystem to route the plurality of tethers from the hub cap to a plurality of deployably extendable and flexibly collapsible arms, where another portion of the decoy tether guide subsystem routes the individual tethers to the respective decoys through indexed tether guides; (c) facilitating coupling and securing an anchor weight to the hub subsystem through looping about at least two line slots defined in a bottom flange of the hub subsystem casing; and (d) facilitating coupling of a motive device to the waterfowl decoy deployment system through at least two line slots defined in a bottom flange of the hub subsystem casing.
